I looking for a way to split my chunk of string every 10 words. I am working with the below code.
My input will be a long string.
Ex: this is an example file that can be used as a reference for this program, i want this line to be split (newline) by every 10 words each.
private void jButton27ActionPerformed(java.awt.event.ActionEvent evt) {
String[] names = jTextArea13.getText().split("\\n");
var S = names.Split().ToList();
for (int k = 0; k < S.Count; k++) {
nam.add(S[k]);
if ((k%10)==0) {
nam.add("\r\n");
}
}
jTextArea14.setText(nam);
output:
this is an example file that can be used as
a reference for this program, i want this line to
be split (newline) by every 10 words each.
Any help is appreciated.

A regex with a non-capturing group is a more concise way of achieving that:
str = str.replaceAll("((?:[^\\s]*\\s){9}[^\\s]*)\\s", "$1\n");
The 9
in the above example is just words-1
, so if you want that to split every 20 words for instance, change it to 19
.
That means your code could become:
jTextArea14.setText(jTextArea13.getText().replaceAll("((?:[^\\s]*\\s){9}[^\\s]*)\\s", "$1\n"));
To me, that's much more readable. Whether it's more readable in your case of course depends on whether users of your codebase are reasonably proficient in regex.
